Rotary Air Lock Feeders

Mashine Dezign & Mfg manufactures rotary air lock feeders used to regulate the flow of material while creating an air lock. They are also used to feed material from silos/hoppers at a controlled rate and are used in number of other pneumatic applications acting as an air lock barrier between the up and down stream. Rotary air lock feeders can also sustain heavy differential pressures and temperature. These are manufactured in different variants such as 'drop-through', 'blow-through', 'off-set', etc. The 'drop-through' or 'in-line' is the most commonly used feeder and suitable for general applications. The 'blow-through' version is used in pneumatic conveying applications where the material is blown away by the incoming stream of air from the pipeline. The 'off-set' type is used to handle particularly hard, uncrushable particles, which jam/seize the rotor during operation. They can be provided with various types of rotors such as fixed-tip, flex-tip, deep-pocket, shallow-pocket, closed rotor, open rotor, etc., depending upon the application. The materials of construction are MS, SS 304, SS 316, CI, cast steel and other special materials, again depending upon the application. The feeders are provided with high performance seals/gland packing, which can be tightened as required by tightening the bolts, and are provided with round/square flanges to match the preceding equipment. For food and pharma industries special, fast cleaning rotary air lock feeders can be provided. The company can customise and design rotary air lock feeders for special requirements.
